I am sorry your experiences with this world building and community have led you to believe as such, Valk. I hope you find space and community which leads you to believe more strongly about their enmeshment. Universalizing your own experiences for dramatic effect (in the weirdest place for a gotcha, too) however, seems to be the most self-aggrandizing action on this page.
Queerness and anti-capitalism are bound in many ways, but capitalism is not found in skin color or gender or sexual orientation, it's merely a form of distributing power. So no, queerness is NOT anti-capitalist axiomatically as there are myriad examples of queer peoples or peoples of other oppressed minorities building their own space amidst the power structure and leveraging it against people with shared identities. This is quite literally: the exact same reasoning Crux employs for asexuality not necessarily being inherently LGBT. Queerness is only anti-capitalist in practicality, in the sense that our current capitalist system serves those who devalue queerness. (coincidentally, how asexuality is queer in practicality in the sense that the predominant function of sexuality in society is based around... having it.)
As for "universalizing my own experiences", I assume you mean the interpretation where you are coming off as morally superior, then you have to truly reflect and see that's what the majority of this entire conflict has ACTUALLY been about. We've been dancing around the tone policing in this thread for days, and I couldn't give a hoot about it under normal circumstances, but when you're trying to be persuasive to people, that's the number one thing that's blocking you from ACTUALLY building a community that is as you describe.
Please don't take my post as a gotcha, it's an attempt to make you recognize the affect you are having and how effective it is in its intentions. I agree with you for the most part, but the conflict going on in this community right now isn't built around ideas, it's built around interpersonal relations. Using rhetoric that is better suited in a speech at a rally to galvanize the undecided to tangible political action isn't going to be as effective in fixing the overall impression that you and crux and the overall "discourse havers" view yourselves as superior in some way.
